The MAGPASS-COAT® process can be used specifically as an equivalent to existing chromating processes. The finishing process produces uniform and contour-true layers and thus even enables the coating of complex surface geometries, such as edges, cavities, reliefs, holes, blind holes or undercuts. It is electrically conductive and serves as an intermediate layer for subsequent treatments such as paints or adhesives.
The chrome-free (VI) passivation SurTec® 650 offers optimum corrosion protection, has low electrical contact resistance and is ideal for after-treatment of anodising layers and as a primer for paints, powder coatings and adhesives.
The aluminium yellow chromating also coats edges, cavities and reliefs uniformly and true to the contour. Even without subsequent surface treatment, the corrosion protection is very good. The coating serves as a bonding agent for subsequent painting. The yellow chromate layer is also abrasion resistant, electrically conductive and weldable. It has an iridescent, light yellow to golden brown appearance.
